Abstract
Description
- This application claims priority from and the benefit of Chinese Application No. 201910870083.2, filed Sep. 16, 2019, the disclosure of which is hereby incorporated herein in its entirety.
- The present invention relates generally to electrical cable connectors and, more particularly, to ganged connector assemblies.
- Coaxial cables are commonly utilized in RF communications systems. Coaxial cable connectors may be applied to terminate coaxial cables, for example, in communication systems requiring a high level of precision and reliability.
- Connector interfaces provide a connect/disconnect functionality between a cable terminated with a connector bearing the desired connector interface and a corresponding connector with a mating connector interface mounted on an apparatus or a further cable. Some coaxial connector interfaces utilize a retainer (often provided as a threaded coupling nut) that draws the connector interface pair into secure electro-mechanical engagement as the coupling nut, rotatably retained upon one connector, is threaded upon the other connector.
- Alternatively, connection interfaces may be also provided with a blind mate characteristic to enable push-on interconnection, wherein physical access to the connector bodies is restricted and/or the interconnected portions are linked in a manner where precise alignment is difficult or not cost-effective (such as the connection between an antenna and a transceiver that are coupled together via a rail system or the like). To accommodate misalignment, a blind mate connector may be provided with lateral and/or longitudinal spring action to accommodate a limited degree of insertion misalignment, or “float”. Blind mated connectors may be particularly suitable for use in “ganged” connector arrangements, in which multiple connectors (for example, four connectors) are attached to each other and are mated to mating connectors simultaneously.
- Another instance of multiple connection interfaces is the use of connectors in “board-to-board” (B2B) connections. In such installations, two printed circuit boards (PCBs) (typically disposed parallel to each other) serve as mounting locations for arrays of coaxial connectors. Because the locations of the connectors are set once the connectors are mounted on the PCBs, there may also be a need for float between mating connectors.
- As a first aspect, embodiments of the present invention are directed to a coaxial connector comprising: a retractable pin, including a cylindrical body defining a first cavity open to a proximal end of the cylindrical body, a retractable member including a second cavity open to a proximal end of the retractable member and a third cavity open to a distal end of the retractable member, and a spring, wherein the spring extends between a spring base and a spring front end within a spring cavity defined by the first and third cavities; an outer conductor body surrounding the retractable pin; and a dielectric layer disposed between the retractable pin and the outer conductor body.
- As a second aspect, embodiments of the present invention are directed to a coaxial connector comprising: a retractable pin, including a cylindrical body, and proximal and distal retractable members extending in each axial direction away from the cylindrical body, and a spring. The cylindrical body defines a center cavity open to both proximal and distal ends of the cylindrical body, the proximal retractable member defines a first insertion cavity open to a proximal end of the proximal retractable member and a first internal cavity open to a distal end of the proximal retractable member, and the distal retractable members defines a second insertion cavity open to a distal end of the distal retractable member and a second internal cavity open to a proximal end of the distal retractable member. The spring extends between a proximal end and a distal end of a spring cavity defined by the center cavity of the cylindrical body and the first and second internal cavities of the proximal and distal retractable members, respectively. The coaxial connector further comprises: an outer conductor body surrounding the retractable pin; and a dielectric layer disposed between the retractable pin and the outer conductor body.
- As a third aspect, embodiments of the present invention are directed to a female coaxial connector adapter comprising: a retractable pin, including a cylindrical body defining a first cavity open to a proximal end of the cylindrical body, a retractable member including a second cavity open to a proximal end of the retractable member and a third cavity open to a distal end of the retractable member, and a spring, wherein the spring extends between a spring base and a spring front end within a spring cavity defined by the first and third cavities; an outer conductor body surrounding the retractable pin; and a dielectric layer disposed between the retractable pin and the outer conductor body. The connector is configured to mate with male interfaces at proximal and distal ends of the connector.

Phrases referring to the “proximal” end or side of an element can be assumed to be referring to a portion that is closer to the P than other portions of that same element, unless explicitly specified otherwise. Similarly, phrases referring to the “distal” end or side of an element can be assumed to be referring to a portion that is closer to the D than other portions of that same element, unless explicitly specified otherwise.
- Referring now to the drawings, a retractable pin, designated broadly at 100, is shown in
FIGS. 1 and 2 . As best seen inFIG. 1 , theretractable pin 100 comprises acylindrical body 102 and aretractable member 104 extending axially away from thecylindrical body 102 in a proximal direction. Thecylindrical body 102 may include a plurality ofaxial slits 101 at its proximal end. In some embodiments, there may be between four and sixaxial slits 101 at the proximal end of thecylindrical body 102. Theretractable member 104 may also include at least oneaxial slit 105 at its proximal end. The outer surface of thecylindrical body 102 may include at least onegrip region 103. Thecylindrical body 102 andretractable member 104 may be formed from a conductive material, such as a metal. - As best seen in
FIG. 2 , thecylindrical body 102 defines acenter cavity 102 c open to a proximal end of thecylindrical body 102. Moreover, theretractable member 104 of theretractable pin 100 defines aninsertion cavity 106 open to the proximal end of theretractable member 104. Theretractable member 104 may also define aninternal cavity 104 c open to a distal end of theretractable member 104. Theaxial slit 105 of theretractable member 104 may extend through the walls of theretractable member 104 that define theinsertion cavity 106. Theretractable pin 100 further includes aspring cavity 107. Thespring cavity 107 may be defined by theinternal cavity 104 c of theretractable member 104 and thecenter cavity 102 c of thecylindrical body 102. Thespring cavity 107 includes aspring 108, which may extend between aspring base 108 b and a springfront end 108 f. - In some embodiments, the
spring 108 may be soldered to the inner surface of thespring cavity 107 at the springfront end 108 f and thespring base 108 b. If thespring 108 is soldered, then thespring 108 may contact both the springfront end 108 f andspring base 108 b at all times without the need to keep thespring 108 in a constant state of compression. Thespring 108 may therefore be in an uncompressed state when no force is being exerting on theretractable member 104. Furthermore, thespring 108 may act as the coupling means between thecylindrical body 102 and theretractable member 104. - In other embodiments, the
spring 108 may not be soldered to the inner surface of thespring cavity 107. In order that thespring 108 may constantly span the full length of thespring cavity 107, thespring 108 may be configured to be in a semi-compressed state even when no force is exerted on theretractable member 104. In order to prevent thespring 108 from restoring to full extension, apin holding mechanism 200 such as that shown inFIG. 3 may be used. - The
pin holding mechanism 200 comprises at least oneinner flange 202 extending radially outwardly from the distal end of theretractable member 104 and anouter flange 204 extending radially inwardly from the proximal end of thecylindrical body 102. The proximal end of thecylindrical body 102 “overlaps” the distal end of theretractable member 104 such that theouter flange 204 is disposed on the proximal side of theinner flange 202. While theretractable pin 100 is in its initial position (i.e. no external force is being exerted on the free end of theretractable member 104 toward the distal end of the retractable pin 100), theouter flange 204 is configured to engage with theinner flange 202. In some embodiments, theinner flange 202 may comprise two inner flanges spaced at a distance apart, known as primary and secondary inner flanges. - As shown in
FIG. 3 , theinner flange 202 may have a substantially triangular cross-section, wherein the distal edge 202D of theinner flange 202 extends radially outwardly from the surface of theretractable member 104 in a direction substantially normal to the surface of themember 104. Theproximal edge 202P of theinner flange 202 may extend radially outwardly at an acute angle from the surface of theretractable member 104 until joining the distal edge 202D at apoint 202T. - The
outer flange 204 may have a trapezoidal cross-section. Aproximal edge 204P and adistal edge 204D of theouter flange 204 may extend radially inwardly at acute angles from the surface of thecylindrical body 102 such that eachedge cylindrical mid-section 204F, which, in cross-section, forms a substantiallyflat base 204F between the two slopededges - Referring now to
FIG. 4 , in other embodiments, apin holding mechanism 210 may include aninner flange 212 extending radially outwardly from the distal end of aretractable member 104′ and having a reversed orientation from theinner flange 202 inFIG. 3 , such that theproximal edge 212P extends in a direction substantially normal to the surface of theretractable member 104′ and the distal edge 212D extends at an acute angle to join theproximal edge 212P at apoint 212T. - The
pin holding mechanism 210 may include anouter flange 214 having a substantially triangular cross-section, wherein the distal edge 214D of theouter flange 214 extends radially inwardly from the surface of thecylindrical body 102′ in a direction substantially normal to the surface of thebody 102′. Theproximal edge 214P of theouter flange 214 may extend radially inwardly at an acute angle from the surface of thecylindrical body 102′ until joining the distal edge 214D at apoint 214T. - As can be seen in
FIG. 5 , some embodiments may include aretractable pin 110 having acylindrical body 112 and aretractable member 114. Thecylindrical body 112 includes at least onecontainment slide 230 s, comprising a firstaxial slot 234 open to the proximal side of thecylindrical body 112, asloping slot 236, and secondaxial slot 239. Thesloping slot 236 extends from the distal end of the firstaxial slot 234 to the secondaxial slot 239. A generallysemicircular groove 238 may be included at the proximal end of the secondaxial slot 239. Theretractable member 114 may comprise at least onelocking peg 232. The lockingpeg 232 may be a punctiform projection, or may be a variety of other shapes, including, but not limited to, a cylindrical or rectangular projection. Furthermore, the at least onecontainment slide 230 s may be a plurality of containment slides 230 s and the at least onelocking peg 232 may be a plurality of locking pegs 232. - As can be seen in
FIG. 6 , some embodiments may include aretractable pin 120 having tworetractable members 124 a, 124 b extending axially outwardly in opposite directions from acylindrical body 122. The cylindrical body defines acenter cavity 122 c. The proximally extending retractable member 124 a defines a first insertion cavity 126 a open to the proximal end of the member 124 a. The proximally extending retractable member 124 a also defines a firstinternal cavity 125 a open to the distal end of the member 124 a. The distally extendingretractable member 124 b defines asecond insertion cavity 126 b open to the distal end of themember 124 b. The distally extendingretractable member 124 b also defines a secondinternal cavity 125 b open to the proximal end of themember 124 b. Theretractable pin 120 defines aninner spring cavity 127 holding aspring 128 extending from aproximal position 128P within the proximally extending retractable member 124 a to adistal position 128D within the distally extendingretractable member 124 b. Theinternal spring cavity 127 is defined by the first and secondinternal cavities retractable members 124 a, 124 b and thecenter cavity 122 c of thecylindrical body 122. Thespring 128 may be soldered, or otherwise maintained, at a soldering position 128S within thecylindrical body 122. Pin holdingmechanisms 200 such as those shown inFIGS. 3-5 may be used to couple thecylindrical body 122 to eachretractable member 124 a, 124 b. Alternatively, in some embodiments, thespring 128 may be soldered to the inside of thespring cavity 127 at theproximal position 128P anddistal position 128D. - As can be seen in
FIGS. 7A and 7B , theretractable pin 100 may be positioned within a female type connector, designated broadly at 300. Surrounding theretractable pin 100 is adielectric layer 304, which is surrounded by anouter conductor body 306. Thefemale type connector 300 may further includeexternal threads 302. A male type connector, designated broadly at 400, may be configured to mate with thefemale type connector 300. Themale type connector 400 includes acontact pin 402 configured to fit within theinsertion cavity 106 of theretractable pin 100. Themale type connector 400 further includes anouter conductor body 408 configured to engage with theouter conductor body 306 of thefemale type connector 300. Acoupling nut 404 may be rotatably retained on themale type connector 400. Thecoupling nut 404 may compriseinternal threads 406 configured to engage with theexternal threads 302 of thefemale type connector 300. - As illustrated in
FIGS. 8-10C , theretractable pin 100 may also be disposed within a female-female adapter, designated broadly at 500. The female-female adapter 500 may have acentral body 502 comprisinggripping surfaces 504 on its outside surface. The female-female adapter 500 may also include twoend portions 506 extending axially outwardly from thecentral body 502. - The
end portions 506 of thefemale type adapter 500 are each configured to mate with amale interface 600, as shown inFIGS. 10A-C . Acentral pin 602 of themale interface 600 is configured to fit within theinternal cavity 106 of theretractable pin 100 within the female-female adapter 500. Anouter conductor body 604 of themale interface 600 is configured to receive and engage with theouter conductor body 508 of anend portion 506 of the female-female adapter 500. The female-female adapter 500 may be fit within acasing 700, as shown inFIG. 11 . The outer surface of thecasing 700 may include several threadedregions 702, which may be used to connect thecasing 700 to a larger cable assembly. - The
retractable pin 100 is configured such that theretractable member 104 is capable of moving axially relative to thecylindrical body 102 and therefore acts as a “floating” pin. As theretractable member 104 is moved axially toward a distal end of thepin 100, thespring 108 of theretractable pin 100 compresses. The movement of theretractable member 104 may be limited by the maximum extent of compression of thespring 108. The inclusion ofaxial slits 101 at the proximal end of thecylindrical body 102 may allow thecylindrical body 102 to expand if theretractable member 104 applies radial contact force to the inner surface of thecylindrical body 102. The expansion of thecylindrical body 102 may allow for a decrease in the degree of Passive Intermodulation (“PIM”) distortion for theretractable pin 100, leading to improved performance. - For a
retractable pin 100 comprising aretractable member 104 including twoinner flanges 202, the inclusion of both primary and secondinner flanges 202 may allow the pin holding mechanism to set two different stop positions. Due to the triangular shape of eachinner flange 202, as theretractable member 104 is pushed toward thecylindrical body 102, theouter flange 204 of thecylindrical body 102 may deflect outwardly over the secondaryinner flange 202. Once force is no longer being applied to theretractable member 104, the substantially flatproximal edge 202P of the secondaryinner flange 202 may frictionally engage with theouter flange 204, thereby preventing further expansion. - With regard to the pin holding mechanism shown in
FIG. 5 , thecylindrical body 112 andretractable member 114 are initially separate and uncoupled pieces. The lockingpeg 232 of theretractable member 114 may be aligned with the firstaxial slot 234 of thecontainment slide 230 s of thecylindrical body 112. The lockingpeg 232 may then be pushed to the distal end of the firstaxial slot 234, at which point theretractable member 114 may be rotated relative to thecylindrical body 112, so as to allow thelocking peg 232 to reach the secondaxial slot 239 via thesloping slot 236. Because thesloping slot 236 extends both radially and distally from the firstaxial slot 234, theretractable member 114 will rotate relative to thecylindrical body 112 while forced toward the distal end of thepin 110. After reaching the secondaxial slot 239, external force on thepin 110 may be removed, allowing restoring force of thespring 108 to push theretractable member 114 radially outwardly such that the lockingpeg 232 is allowed to rest in thesemicircular groove 238 and thus to act as a stop. This mechanism may allow theretractable member 114 andcylindrical body 112 to be coupled and decrease the time and/or cost required to create theretractable pin 110. - As shown in
FIG. 7 , theretractable pin 100 may be situated within afemale type connector 300. As amale type connector 400 is brought into contact with thefemale type connector 300, thecontact pin 402 of themale type connector 400 may fit within theinsertion cavity 106 of theretractable pin 100. The engagement between thecontact pin 402 and the inner wall of theinsertion cavity 106 causes theretractable member 104 of theretractable pin 100 to be pushed to the distal end of thefemale type connector 300, causing thespring 108 to compress. In order to keep theconnectors coupling nut 404 rotatably retained on themale type connector 400 may be rotated such thatinner threads 406 of thecoupling nut 404 engage withouter threads 302 located on the outside surface of thefemale type connector 300. The restoring force of thespring 108 is unable to cause sufficient force so as to separate the twoconnectors coupling nut 404 has been threaded over thefemale type connector 300. - The “float” characteristic of the retractable pin within the
female type connector 300 or within a female-female adapter 500 may allow the contact pins 402 ofmale type connectors 400 to be effectively galvanically coupled with thepin 100 of thefemale type connector 300 when themale type connector 400 is within a relatively wide range of distance away from thefemale type connector 300. The “float” characteristic may be particularly advantageous in situations in which themale type connector 400 has its position set before connection such that it may be incapable of being brought within a narrow range of distance from thefemale type connector 300. - The use of a
retractable pin 120 with tworetractable members 124 a, 124 b, as shown inFIG. 6 , may be useful in combination with a female-female adapter 500, as thepin 120 may allow for a “float” characteristic on both ends of theadapter 500. This may be particularly useful for a situation in which twomale interfaces 600, which are both to connect to the female-female adapter 500 are positioned at a set distance apart before interconnection. This distance may be too close or too far apart for existing adapters to accommodate bothinterfaces 600. The “float” characteristic may therefore allow bothmale interfaces 600 to connect through the same female-female adapter 500. - For a
retractable pin 120 with two retractable members 124, it may be useful to solder theinternal spring 128 to an inner surface of thespring cavity 127 at a soldering points 128S with thecylindrical body 122. Soldering thespring 128 may decouple the proximal and distal ends of thespring 128, allowing the “float” characteristics of eachretractable member 124 a, 124 b to not interfere with one another. - Embodiments of this invention are not intended to limit the use of the
retractable pin 100 to female type connectors. In some embodiments, theretractable pin 100 may be used as a contact pin for a male type connector. - Those of skill in this art will appreciate that the
retractable pins 100 discussed above may vary in configuration. For example, thepin holding mechanism 200 may comprise primary and secondaryouter flanges 204 affixed to thecylindrical body 102 instead of or in combination with primary and secondinner flanges 202, so as to create two stop positions. Furthermore, those of skill in the art will appreciate that theinner flange 202 may be spaced some distance away from the end of theretractable member 104, and theouter flange 204 may be spaced some distance away from the end of thecylindrical body 102. - Those of skill in this art will appreciate that, though only a
retractable pin 100 with a singleretractable member 104 is shown inside of a female-female adapter 500, apin 120 with tworetractable members 124 a, 124 b may also be used in conjunction with the female-female adapter 500. Similarly,retractable pins 100 with any manner ofpin holding mechanism 200 herein described or those wherein thespring 108 is soldered to the inner surface of thespring cavity 107 may be used in conjunction with the female-female adapter 500 or thefemale type connector 300. - The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although a few exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims, with equivalents of the claims to be included therein.
